39.4 Wireless Internet Access
What factors may cause intermittent or unstabled wireless connection? How can I solve this
problem?
The following factors may cause interference:
• Obstacles: walls, ceilings, furniture, and so on.
• Building Materials: metal doors, aluminum studs.
• Electrical devices: microwaves, monitors, electric motors, cordless phones, and other wireless
devices.
To optimize the speed and quality of your wireless connection, you can:
• Move your wireless device closer to the AP if the signal strength is low.
• Reduce wireless interference that may be caused by other wireless networks or surrounding
wireless electronics such as cordless phones.
• Place the AP where there are minimum obstacles (such as walls and ceilings) between the AP and
the wireless client.
• Reduce the number of wireless clients connecting to the same AP simultaneously, or add
additional APs if necessary.
• Try closing some programs that use the Internet, especially peer-to-peer applications. If the
wireless client is sending or receiving a lot of information, it may have too many programs open
that use the Internet.
